Overall it looks good and sounds pretty cool. I was not aware that I would hear the vaccuum after I installed it. There was only one problem, and that was that the box slightly dented the brace in the hood. About a dime size and it did not go through the hood itself, but I will have to rust proof the ding. There is increased gas mileage on the freeway, no doubt about that.
